Hopefully the following information will be useful when you begin the challenge of growing brugmansia seed at home. It is fun, challenging, and rewarding when you see the end result.
One of the first things you should know is that your seed will not be exactly like any other brugmansia plant. If you are expecting it to look like the plant the seed pod was on, it probably won't. There can be a lot of similarities, but nothing identical.
A Good Harvest
Brugmansia seed is a funny little seed with a corky covering that hides the little bean that is actually what starts the brugmansia plant. They range in size and color, depending on the type of seed that is available to you. Some are tiny and some are quite large by comparison. Some are very light brown and range to very dark brown.
To begin with, you will need to have a good potting medium that will not stay too wet. Something that has good drainage is a must. Generally it is easiest to plant several seeds in a small plastic pot of four to six inches in size. Fill the pot to within an inch and a half with potting soil and moisten it. Set it aside because there is more than one way to do this.
One way to start the seeds is to just plant them, cork and all. You can do this right from the seed pod, from seed you have received from a friend or ordered, or some of your own that you have allowed to dry a while. Seed is viable for quite a long time, although the germination rate does decrease with time. If you chose to plant this way, lay the seed on the soil surface and then cover with about a quarter to one half inch of soil. Moisten the top soil and place the pot in a warm place to wait for germination. This can take from two week to several months, but most will germinate within a month. Keep the soil just slightly moist until the babies start coming up. Misting the soil is better than watering it. Still, do not over water as too much moisture can contribute to a problem called "damp off". That is where the newly emerged seedlings just seem to fall over. Good air circulation is important to keep this from happening. Always be sure to mark your seeds with the cross they are (mother plant first and father plant, or pollen donor second) and the date you planted them.
